# NB: For a naive exact match, there is a race condition here, as
# 518.out expects exactly three evaluation rounds to be complete by the
# time the following operation is invoked.  If sudo/pmie is too slow,
# it'll lose the race (actions<5).  If this thread is too slow, pmie
# will go ahead (actions>5).  So we tolerate values in the range 4,5,6-9
# for the true, false and action counts, but the counts for each must
# be equal.
